Motenergy ME1302

Hey everybody,

My name is JD and I am new to electric motorcycles and electric motors in general really haha. I have a KX65 collecting dust in my garage and would like to do an electric conversion to it and use it mainly as a after hours pit bike on my backyard track. I have seen a couple mini-bike conversions using modded oset motors etc. but I want the bike to have power equal to around 20hp +/- and was told a water cooled brushless motor would be my best bet. I have been looking at this ME1302 model and was wondering if it would be total overkill or a good option for my project. here is the description from the web store:

Designed for long life. No brush maintenance. The motor is 92% efficient at voltages between 24 to 96 VDC. Continuous current of 125 amps AC (180 Amps DC into the motor control). This is a 3-phase, Y-connected Permanent Magnet Synchronous Motor with an axial air gap. It has two stators with a rotor in the center.

Most of this might as well been chinese as far as my understanding goes but i've ordered a couple books on electric motors and electric vehicle conversions to hopefully change that but what i did see was a peak stall torque rating of 60 ft/lbs and that seemed like wayyyyyy to much for a pit bike. Can you adjust power delivery with a controller and battery set up or am I on the wrong track with a motor like this?

OoooOOoo. I was going to quip something about overkill being impossible, until I looked up the bike.

Yeah, that's a badass motor that I'd put into at least a 350cc frame, but more better a 600cc frame. I'd say for a mini-bike mini-cycle type of thing, I'd be going with a brushed, smaller, cheaper motor, but I can't seem to find a Motenergy that's lighter. Too bad you couldn't find an original ETEK, that'd be perfect.

wow thanks for the quick responses guys! and no, I am not trying to go 70 hahaha I would be happy with 45. My goals for the build are 1. being able to out pace my stock KLX110 2. getting around 45 min of ride time per charge 3. keeping weight and handling characteristics as close to or better than an i.c.e bike as possible. I checked out the ME0909 and it sounds like a great option, the supplier said they have put them in mini bike before and they feel significantly faster than a stock XR100 so I'm thinking this might be the motor I need.

I think that (at 3000 RPM!) could get you going fast enough to scare the b'jeesus outta you (isn't that the point?), and it's only 17lbs or so, 6" in diameter, and cheap. It has a liquid cooling, and a 72V option too. You could run it dry, it leaves more room for batteries, and you can add cooling if it starts getting all melty. I haven't used the Goldens, but I know they're not uncommon for the smaller mini and bicycle conversion builds.

Thanks for throwing a wrench in my sales pitch, Ted!
45 minutes of ride time would need a big battery pack, even with the golden motor, IMO.
But Ted is right, the Golden will be much better than an old 0909

I can send it to you as a gift....might save you some money on import fees. I only want 125 bucks for it. I don't know how much shipping will be. I'll even throw in a contactor, fuse and suppression diode as a package deal for you. If you decide you want it, send me in a private message your address and I will see what it will cost to send ...won't be cheap I'm sure
